Need help with 1986 Ford starting harness color codes

I am installing an aftermarket push button starter in my Class A, and need help in identifying the wiring in the steering column. This is a 1986 Ford, and it probably has an F-350 harness.
I have identified the yellow wires as the 12v feed, but need to know which wire is start, ACC, on, ground, etc. I don't want to fry anything by experimenting, and the location of the connection block makes it impossible to take continuity tests.
